repl.it does not support System.UI namespace in C#?

Error message from compiler:

There's a few reasons why it shouldn't work.

repl.it is a terminal-based site. There is no UI involved.
System.UI doesn't even exist.
- If you meant to use Windows.UI, you can't because repl.it runs on Linux.

I understand that GUI-related classes should not work here, but I expected it to be able to play with some IO stream classes like TextWriter.

Thanks for reply.

TextWriter uses System.IO, not System.UI

Hi !

I never worked with C#, but If something is missing try https://repl.it/bugs or https://repl.it/feedback

If you want to use graphical things on C#, ask on the feeback board
